【摘要】：作为城市交通管理与控制的热点问题及重要组成,交叉口的信号控制方法受到行业的广泛关注,如何合理利用有限的时空资源科学地探索和挖掘城市道路交通潜力,改善交叉口的总体交通运行状态,成为现阶段城市交通领域的研究重点。本文以平面交叉口进口道综合待行区为研究对象,在综合待行区设置条件、车辆行为分析、交通运行效益评价、预信号控制策略及控制效果仿真分析等方面进行了相关研究。论文首先对国内外关于平面交叉口控制方法、待行区控制、预信号控制及交通仿真分析等方面的研究成果进行总结;随后对综合待行区常规的设置方法进行概述,在此基础上对其设置的几何条件、流量条件及控制条件进行分析,进而对综合待行区的交通流特性进行行为建模;根据评价指标的选取原则,对饱和度、通行能力、延误、停车次数及燃油消耗量等交通运行效益评价指标进行理论分析,说明了设置综合待行区对交叉口的优化控制效果;在前文基础上,提出了基于交通波理论的综合待行区车辆排队模型,并建立了考虑排队约束的综合待行区主、预信号协调控制方法,随后基于层次分析的概念提出了综合待行区的感应控制策略;最后,借助先进的微观交通仿真软件VISSIM对上述各部分的理论研究成果进行仿真建模、评价结果验证及算例分析,充分证明了理论研究成果的有效性。论文的研究结果表明,对符合设置条件的平面信控交叉口设置综合待行区可以较明显地提高其通行能力、降低延误从而改善整体的交通运行状况;但由于综合待行区的特殊放行规则,相对于传统交叉口控制方法,平峰时期综合待行区的设置无法避免地会导致停车次数及燃油消耗量的增加;因此,综合待行区的实际运用需配合合理的优化控制策略,从而充分发挥综合待行区的控制优势,其中包括主信号与预信号之间的协调控制策略及待行区全感应控制策略。
[Abstract]:As a hot issue and an important component of urban traffic management and control, the signal control method of intersection has been widely concerned by the industry. How to rationally utilize the limited space-time resources to explore and excavate the urban road traffic potential scientifically, and improve the overall traffic running state of intersection. This paper takes the integrated waiting area of the intersections as the research object, sets the conditions in the comprehensive waiting area, analyzes the vehicle behavior, and evaluates the benefit of the traffic operation. The pre-signal control strategy and simulation analysis of control effect are studied. Firstly, the control methods of intersections at home and abroad, waiting area control are studied. The research results of pre-signal control and traffic simulation analysis are summarized. Then the general setting method of the integrated waiting zone is summarized, and the geometric condition, flow condition and control condition are analyzed on the basis of which, and then the behavior model of the traffic flow characteristic of the integrated waiting area is established. According to the selection principle of evaluation index, the evaluation index of traffic operation benefit, such as saturation, capacity, delay, parking times and fuel consumption, is analyzed theoretically. The optimal control effect of the intersection by setting the comprehensive waiting area is explained. On the basis of the above, a vehicle queuing model based on the traffic wave theory is proposed, and the coordinated control method of the master and pre-signal is established. Then, based on the concept of AHP, the inductive control strategy is put forward. Finally, with the help of the advanced microscopic traffic simulation software VISSIM, the theoretical research results of the above parts are simulated and modeled, the evaluation results are verified and the numerical examples are analyzed. The results of this paper show that the comprehensive waiting area of the plane signal-controlled intersection can obviously improve its capacity. Reduce delays to improve overall traffic conditions; However, due to the special release rules of the waiting zone, compared with the traditional intersection control method, the setting of the integrated waiting zone in the peak period will inevitably lead to the increase of parking times and fuel consumption. Therefore, the practical application of the comprehensive waiting area needs to cooperate with reasonable optimal control strategy, so as to give full play to the control advantages of the comprehensive waiting area. It includes the coordinated control strategy between the main signal and the pre-signal and the full induction control strategy of the waiting area.
